Definitions

  • the present invention relates to a high performance boat.
  • Performance is understood to mean the maximum speed of a boat (especially for sailing boats) or the ratio of the boat's speed to the energy supplied for its advancement (in particular for motor boats).
  • This device has the disadvantage of having to be adjusted by hand and does not allow permanent adjustment of the position of the flap as a function of the speed.
  • the object of the present invention is to produce a hull whose shape continuously adapts to the relative speed of the water and the boat.
  • the subject of the invention is a boat with high performance, at least a rear part of the hull of which is capable of pivoting towards up or down between a low position where the pivoting part of the hull is in line with the central part of the hull and a high position where the pivoting part is in line with the rear part of the hull , characterized in that said pivoting part is associated with means for returning to the high position.
  • the return means is obtained by the inherent elasticity of said pivoting part.
  • the pivoting part is then made of a plate of flexible and elastic material.
  • the plate may include at least one recess projecting from the side opposite to the hull and ensuring the flow of water between the plate and the hull.
  • the return means is produced by the buoyancy of said pivoting part.
  • the pivoting part is associated with an elastic return means towards the bottom.
  • the pivoting part is associated with a means of communication with the atmosphere.
  • the means is a chimney made in the hull of the boat.
  • the means is a groove made in the hull of the boat.
  • the buoyancy volume is greater than one third of the volume between the pivoting hull part in the high position and the buoyancy plane of the boat.
  • FIGS. 1A and 1B show, seen from below in perspective, a hull 1 of a boat according to the invention.
  • a portion 10 of the shell is pivotable between a high position (fig. 1 ⁇ ) for low speeds, and a low position (figure 1B) for high speeds.
  • the reference 11 designates the pivot axis, produced in practice in the configuration of the figure by two joints 11A and 11B.
  • the pivoting part is associated with a means for returning to the high position.
  • the return means is the inherent elasticity of the pivoting shell portion, which is made of a plate 2 made of elastomeric material such as rubber or plastic, such as polyterephthalate d 'ethylene glycol, or more generally in flexible and elastic material.
  • a chimney 3, formed through the hull, makes it possible to communicate with the atmosphere the volume between the plate and the portion of the hull which is opposite.
  • the plate is fixed to the hull preferably by gluing.
  • the plate comprises at least one step 30 which ensures the flow of the water comprised in the volume located between the plate and the shell, as well as that contained in the chimney 3.
  • Figures 3A and 3B explain the operation of the device. At speeds below the critical speed, ( Figure 2A), the plate remains pressed against the hull under the action of its own elasticity.
  • FIGS 4A and 4B show an alternative embodiment of the invention.
  • the pivoting shell portion is here referenced 21 and rotates around a hinge 22.
  • the dashed line delimits the pivoting shell portion which has the general shape of a gutter portion.
  • the return means here is the buoyancy of the hull portion, obtained by fixing above this portion a block 24 of material lighter than water, such as plastic foam or rubber.
  • Operation at high speeds is further improved by providing the pivoting portion with a return means, such as an elastic cable 25 stretched between a fixed point 26 of the shell and a point 27 linked to the pivoting portion.
  • a return means such as an elastic cable 25 stretched between a fixed point 26 of the shell and a point 27 linked to the pivoting portion.
  • FIG. 5 shows an alternative embodiment in which the pivoting part comprises two halves 31A, 31B, symmetrical with respect to the plane of symmetry of the boat and articulated around axes 32A and 32B.
  • the pivot axes can be horizontal as shown in Figure 6, or oblique as in Figure 7.
  • the pivot axis or axes can be in the plane of the flat bottom of the boat.
  • the communication between the atmospheric air and the volume located between the hull and the flap is an important element of the invention, since it conditions the elimination or at least a strong reduction of the depression at the rear of the boat.
  • This communication can be improved, as shown in FIG. 9, by practicing on the surface of the hull 50 of the boat, at least one groove 51 in communication with the atmosphere by the chimney 53.
  • the mobile part has been referenced 52 in this figure.
  • this groove can extend along the hull to a point located in the open air.
  • a buoyancy volume is preferably chosen which is greater than a third of the volume comprised between the pivoting part of the hull in the high position and the waterline of the boat.
  • FIGS. 10A and 10B show, respectively in the high position and in the low position, an alternative embodiment in which the pivoting shell element is produced by a mass 40 of deformable plastic material, which deforms under the combined action of its own elasticity and Archimedes' forces.
  • This mass is preferably bonded to the boat by a portion 41.
